Why buy Reflex One Stop Xtreme 4.5Kg?

One Stop XTREME – The hardcore muscle builder

Reflex Nutrition’s most hardcore muscle building supplement in our 15 year history. Designed to outperform all other muscle building formula it is THE product for people wanting to pack on mass fast. It is the only product to contain the exclusive Quattro® protein blend with every single batch lab tested for protein content.

55g of Quattro® time-release protein
Arguably the most sophisticated protein blend in existence that you won’t find in any other product. Quattro® is unique to one stop XTREME, exclusively from Reflex Nutrition. It consists of three different types of whey protein in conjunction with pure undenatured micellar casein. Four of the best!

Contains organic & low GI sources of carbohydrates
The primary carbohydrate content of one stop XTREME is provided by a unique complex of organic oats and barley with naturally occurring vitamins, minerals and dietary fibre. Added to this is the designer low GI carbohydrate trehalose; this provides your body with a very stable long lasting form of carbohydrate that will help prevent gains in fat whilst also providing the increased energy that is needed to fuel intense training sessions.

Contains an added 3,000mg** of mTOR anabolic L-leucine
Of all the essential amino acids the branched-chain amino acid L-leucine is the most potent. L-leucine is scientifically proven(1) for its ability to initiate biological signalling via mTOR (mammalian target of rapamycin) - in simple terms it can trigger increased protein synthesis when combined with whey hydrolysate and carbohydrate taken after resistance exercise.

Every 145g serving provides a huge 10,500mg dose of BCAA’s
Because one stop XTREME contains such a potent complex of whey peptides and whey fractions it therefore contains naturally high levels of branched-chain amino acids. Just one serving provides 10,500mg of BCAA’s! Branched-chain amino acids are scientifically proven to increase protein synthesis, increase workout capacity and aid in recovery.

5,000mg** of patent process Creapure® creatine monohydrate
Nearly all of the scientific studies(2) relating to increased muscular strength, increased power, increased endurance and increased lean body mass have one thing in common. They all used Creapure® creatine monohydrate. That is because Creapure® is recognised as the best quality creatine monohydrate available today, providing a patented solution to your strength and growth goals. Whilst other supplements contain different forms of creatine like creatine ethyl ester (CEE), none of these other forms have ever been proven to outperform Creapure® creatine monohydrate.

Research proven levels of beta-alanine
The harder, more intensely you train, the greater performance and results. However, with intense training comes lactic acid, ammonia and acidity build up. Beta-alanine is a precursor to carnosine which helps to buffer acidity/pH changes within muscle tissue. Scientific studies(3) have proven that beta-alanine decreases fatigue in athletes and increases total muscular output. Industry leading doses of 1,800mg beta-alanine are found in just 1 serving of one stop XTREME.

10,000mg of the most biologically available form of glutamine
10g of glutamine peptide, a potent source of glutamine, which is credited with anti-catabolic and immune support. Glutamine peptides are absorbed by the body more easily than normal L-glutamine. This is especially important in an all-in-one formula where protein and other amino acids will compete for absorption.

Contains a full complement of vitamins
100% of the RDA of vitamins which makes it unique in the all-in-one market.

Strength-boosting magnesium with testosterone-supporting zinc and avena sativa one stop XTREME contains zinc monomethionine, the highest known quality form of zinc. This is instead of the cheaper, less easily absorbed zinc oxide. Avena sativa is included to support healthy testosterone levels. Magnesium, in the high quality form of magnesium citrate (instead of magnesium oxide) is included in the formula to help boost strength and energy production.

Contains stable probiotics, digestive enzymes and a bioavailability enhancer LactoSpore® probiotics are added for gut health and Digezyme® digestive enzyme complex is added to help the body digest these performance ingredients more efficiently. Also included is BioPerine® a patented and natural bioavailability enhancer to ensure your body gets maximum absorption of the nutrients contained in one stop XTREME.

“ In my opinion the best value for money out there although it tastes pretty bad!! I have tried alot of all in one's and this is the most superior because of the amount of supplements you get in 1 shake for the price. Don't let the taste put you off. ”

“ 4 scoops per serving? something not so good here, if you add 4 scoops of any protein you'll get just as much protein/ carbs/ creatine etc. taste was nothing short of foul. value isn't too bad for 4.5kg but when you're adding 4 scoops you need it. want my advice? stick with, or move to PHD Synergy iso 7! Best product on the market in my oppinion. ”

“ No major gains to report on this, I found USN to work much better. Strawberry doesnt taste good at all, as for mixing, it doesnt, you get alot of what looks like oats at the bottom of the shake which isn't pleasant to drink. As for value, 4.5kg sounds good but its not alot when you have to add 4 scoops. ”

“ Yep, a real nose-holder this one. Taste is like flour and water with a bit of coco in it (chocolate flav). I seem to have made similar gains using OmniMXHardcore which is cheaper and tastes better. No wonder you put on mass when using 8 scoops per day.. mind you a slightly smaller scoop than other brands. So im not fully sold, but also think it has some good benefits.. but end of the day you gotta drink this stuff twice a day and its not pretty! Im going back to OmniMXHardcore sorry. ”

“ Currently my All-in-One of choice. My reasons are that they use good clean carbohydrates derived from oats and barley which has all that natural vitamins and minerals. A good dose of L-Leucine for protein uptake. By far the best reason is that they use Crepure creatine from Germany which I find the highest quality of its kind. The taste is good (Strawberry), but really if something works and you are serious enough. The taste is a minor thing. Other reviewers complaining about the taste are in my opinion are a bunch of girls. My only gripe is that its a post workout shake so why have they added Beta-Alanine? ”

“ Awesome product, if you know your stuff you know this has got a solid ingredients list, unique to other 'all in ones' People complaining about serving size need to understand you can't get 50g protein 70g carbs 10g glutamine 10g bcaa 3g leuicne into 1 scoop, a serving is a serving. Gone few quite a few bags of this now, made good gains, improved my strength and maintained it. Recovery also improved. To prove I'm not employed by reflex or monster il say the taste could be better, not as nice as maximuscle or phd but bare able and you get used to it. ”

Ask a Question
Hi lads just a quick question im currently doing a bulking course and i was just gonna purchase this do you think its as strong as muscle fuel anabolic and phd synergy? which do you prefer? Regards
Hi Daniel The one stop and synergy are very similar. For bulking up I would always recommend the muscle fuel anabolic. Kind regards Mikael phd


Hi lads, I'm debating buying this product but how long will this tub last? best wishes
Dear W, There is approx 31 servings (145g per serving) in this bag. Dave


Hi guys, just wondering if this is product is drug tested for rugby players? Im looking to bulk up and increase my strength and power but not sure if this product is allowed?
Hi Ben, This product is safe to take for Rugby. It does not contain any illegal substances. However, if you are in doubt, consult your governing body about controlled substances then check the ingredient profile of One Stop.


Could I get ripped from this product too?
Dear Leigh, This is more of a product you would be looking at to get the 'ripped' look. An all in one lean muscle builder is great for helping to harden the muscle and build lean muscle. Dave


Hi, can you stack one stop extreme with zinc matrix and bulgarian tribulas, cheers
Hello James, These are fine to stack together and would yeild some good gains in strength and size. Best regards


Hey team monster, Just a quick query I'm training for a mens health cover shoot, whilst rugby training for a division one side, so the two contradict, due to the barb content will this impede on gaining the coveted lean physique ?? or will this still be a good product to use like synergy?
Hi Warren I have found that with this product it is completely dependant on how you fit it in with your diet. if you use it to fit in with your maintenence calorie level you will probably put a little bit of muscle on how ever if you drop your carbs it can help maintain your muscle mass whilst dieting. so it really is completely up to you. it would certainly help your rugby. thanks Yours in health


Hi lads, I was wondering how much of this you would recommend to take on a gym day and when to take it? Seeing as each serving is 145g would it not be better to take only half a serving on a gym day as there are only 30 servings? Thanks
Hi Ken. You could use half a serving if you saw fit. It would depend on your overall diet. If you are eating enough, then you can half half a serving. If not, then have a full serving to ensure you get the most calories in your diet. Thanks, Omar.


As a lean gaining supplement onlys used as a meal replacement in off days and a post workout on training days is this better than muscle fuel anabolic?? Kind Regards Warren
HI Warren. This product is great for meal replacement and for post workouts. I would rate it just as good, if not better than muscle fuel anabolic. Thanks, Omar.


Is it ok to use this once every week or every 5 days after exercise to aid recovery? Rather than buld bulk.
Dear James, For best results use 1-2 times every day. Once weekly will not aid recovery. Dave


Hi, what is the difference between reflex one stop and reflex one stop extreme? thanks
hi sak. the one stop extreme is a higher calorie product so better for gaining muscle and weight. Best regards -AC-


Hi...How many scoops should I take per serve ?? if im mixing with water whats the procedure ? or if its milk ??
Dear Hussain, You want to be having a 145g serving per serving in water. Dave


Hi lads, im bulking atm and was wondering if this would be better post-workout of growth matrix? cheers
Hi Joe, It would be good post workout because it is an all in one and has glutamine BCAA's etc in there i personally would use the PHD recovery as it is made specifically for post workout receovery. Kind Regards Liam


I'm an ectomorph and want to bulk up considerably. Do you recommend me using this product as well as critical mass?
Dear Ned, This would provide a good post workout shake for you yes. It is an all in one, but is high in kcals too. Dave


Hi guys, could this be used along with growth matrix?
Hello Joe, Thank you for your question. These two products would be a really good stack. The Reflex Growth Matrix would be ideal post-workout while the One stop xtreme would be effective when used pre-workout. Yours in health, Jack Gray.
